Specification of Letters Patent.v Pai-@nigga Spi, 12, 19105, Application filed March 4, 1915. Serial N0. 12,104.

An air compressor cylinder 11 is arranged above the casing 1 2 and coaxial there-` wlth, the cylinder being supported by rods 12 connected at one end to the cylinder and at the other end to the well casing. ring A 13 of angle material is arrangedin'termediate;` the ends of the cylinder, the ring having one portion fitting the cylinder and sevx cured thereto in any suitable or desired manner and a portion extending perpendicular therefrom t which the upper ends of the -rods are connected. Thev rods l2 are four in number being arranged at angular intervals of 90 and the lower ends of the rods are passed through the head 5 and through a :liange 1i at the upper end of the T and are secured to the ,head and flange in any suitable manner. C'

The upper end of the cylinder 11 is closed the head being secured to the' cylinder by' means of a ring 16 The ring has a portion fitting the cylinder and a portion extending at right angles thereto abutting thejunder fae of the head. The lower end ofthe cyl- 1n er is closed as indicated at 17 and-a stuif ing box 18 is arranged at the oenter'of the head. and at. the axis of the cylinder.l l

A foot valve is arranged at the bottom of the well casing in the section 2 and the said foot valve comprisesaring 19 fitting within a seatrZO within the ca and a rin/g 21 has a threaded engagement withlthe ring 19 above the seat. The ring supports a central f sleeve 2 2 above the same and at the axis of the ring by means of arms 23, said arms bev'ing integral at one end with the ring and at the other with the sleeve. .Each arm is provided on its inner face with a guide rib 24 and a disk valve' 25 is arranged between the arms, the valve having radial notches 26 for engaging the ribs to guide the valve in" its rising and falling movement. The valve normally restsupon the upper end of the ring and'it will be obvious'tha't when the water is drawn upward through the ringthe said water will llftthe valve and will flow past the same into the casing 1 -2.

A plunger is provided for llftlng the water, the plunger Acomprising a ring 27 externally reduced and threaded at its upper end,

and the said reduced portion is engaged 'by a ring 28. The ring 28 supports al1 internally threaded sleeve 29 above the ring 27' l and at the axis of the casing 1--2 by means of arms 30, the arms being integral at one end with the ring and at the other with the sleeve. Each arm is provided on its inner face with a guide rib 31 and-a disk valve 32a is arranged between the arms, the valve having radial notches similar to the notches 26 of the valve 25 for engaging the .ribs to guide the valve in its rising land falling movement. A piston rod 32 has a threaded i engagement at its lower end'with the sleeve v stantia 29 and the upper end of the rod is enlarged to form a head 33 which ts within the lower end of a hollow plunger rod 34 and is secured `thereto Ain any f suitable or desired manner. The upper end of the hollow rod .34 extends through the stuffing box 18 into the compressor cylinder 11, and a piston or `plunger is secured to the said rod in the .2o

' valve. normally resting on the ports 38 for closing thepsame and the valve is normally pressed downward by coil springs 40, the

said springs being arranged between the valve and the disk 37. The ringvalve is guided in its movement by vertical guide ribs 41 on the inner surface of the body 35 of the plunger, the said ribs being arranged at angular intervals of 90 with respect to each other.

Near its lower end the compressor cylin- I der 11 isfprovided with four laterally exinlet ports for thecylinder. Each nipple. 45 is internally threadednear its outer end to I hasv an annular series of openings44 and a .l

central opening for receiving the valve stem 45. A valve` 46 is Aconnected with tending nipples 42, the said nipples formingl receive a threaded plug 43, and each -plug each stem on the inner side of the plug and 'o a coil spring 47 encircles each stem between the outer end of the plugand a stop 48 adjustable along the stem.

It will be obvious thatwhen the plunger 35-37 moves upward, airxwill be drawn intol the lower end ofthe cylinder through the y ports or passages 43 of the plug, the air rush' ingl in and opening the valves 46. As the piston movesv downwardthe air will enter the hollow body of the piston, lifting the valve 39 and will pass intothe bore of the hollow. rod 34, the said bore communicating freely' 'with the interior of the piston... The air will pass down through the hollow -tube 34 and "11 be delivered. the casing 1-2 below lthe level of the water through the elbows v 49. Each elbow has one arm threaded externally to engage an opening 50 in the wall 4of the hollow rod, and the other arm is internally threaded as indicated at 51 and the said arm extends upwardly approximately parallel with the axis ofthe rod 34. ,A valve seat 52 is formed in each elbow at the junction of the arms and aball valve 53 cooperates with each seat, normally resting on the seat to permit the air to pass out of the rod and to prevent the water passing into the rod.-l Four of the elbows 49 are pro vided, the said elbows being in fact check valves for permitting the air to pass out from the rods and for preventing the entrance of water or airto the rod. A cross head is connected with the rod 34 above the heads 5 -of the casing 1 2, the said cross head 54 having a central opening 55 for receiving the rod 34, and the cross head is secured tothe rod. The cross head is also provided with openings 56 near its ends for engagement 'by oppositely arranged lrods 12, and outside of the openings-561 each end of the cross head has a head 57 connected to the rod by a reduced portion, as shown'. A

l pair of standards or uprights 58 is arranged adj acent to the casing 1-2, the standards or uprights being supported by a base 59, which has an opening through which the upper section 1 of the casing 1-2 passes.

The casing is supported ini fixed position with respect to the base by eans of a sectional clamping member or ring 60 which is clamped on the section 1 below the ange 10 and the clamping ring, rests u on the upper face of the base. The stan ards or uprights 58 are connected by a cross beam 61 which is secured to-the respective standards by bolts and nuts 62, and bearings 63 are arranged on the beam at the top of each standard.\)

A walkln beam 64 is arranged between .the standar s, the beam having jounnal pins 65 which are journaled in the bearings 63. The beam is forked at one'end and the arms 66 ofthe fork have links 67 pivoted thereto at one end of the link, the other end of each link being journaled on the reduced portion of the cross head between the adjacent head 57 and the body of the cross head. The other end of the beam is connected to a crank'arm 68 on a crank shaft 69 by means of thelink 70, the link being pivoted at one end to the outer end of the walking beam and at the other end to the crank arm. The crank shaft 69 is journaled in a sup orting base 71 and a gear wheel 7 2 is secure to the shaft intermediate its vends 'and the gear `wheel meshes with a pinion 73 on another Lies/,ere

shown) which in turn is connected-to the piston rod of a gasolene engine indicated at 77, in the usual manner.

It will be obvious that when the engine 77 is running the crank shaft 74 will be rotated and will in turn rotate the crank shaft 69, but at a lower rate of speed through the gear and' pinion connection 72-73. As the crank shait 69 rotates the walking beam 64 will be vibrated and the plunger rod 32-34 will be reciprocated to reciprocate the plungers in the-casing and 1n the compressor cylinder. When the plunger 27 moves downward thewater above the foot valve will lift the valve 32, and will pass through the plunger to the space `in the caslng 1-2 above the plunger.

When the plunger moves upward the water above the plunger will be lifted and water will'rush in from the well intake at' lower end of the cylinder 11.

valves 46 and said air will lift the ring When theplunger or piston 35. moves downward the air within the lower end of the cylinder cannot passout by way of the valve 39 and will pass. into the chambered body of the piston or plunger and into the hollow rod 34. This air in the hollow rod 34 will finally lift the valves 53 and will pass out into the water, thereby aerating the water. The perforated head 15 of the cylinder 11 is for the purpose of equalizing thelpre'ssure on the plunger and to prevent any airco'mpression or. partial vacuum between the said head and the plunger. The

particular connection between the rod 34 1 deli-vering it at the point where it is needed.
